6-1 Angles & Radian Measure:
This section had three learning goals. First, I learned how to do conversions of degree measurements to radians, and vice versa. To convert to radians, you multiply the angle measure by pi/180. To convert radians to degrees, you multiply the angle measure by 180/pi.
Next, we also learned how to find arc length, s, which is the radius times the central angle.
Lastly, we learned how to find the area of the sector which is the product of (½)(radius-squared)(angle).

My learning goal this month was to learn how to graph trigonometric functions: sine, cosine, tangent, cotangent, cosecant, and secant. I am getting more comfortable with graphing and finding equations for graphs. It is very helpful for me to identify the parts of the function, then I can easily find the amplitude, period, phase shift, vertical shift, the starting point and end point for the graph of one period.
